'The 'free ends of the type bars 1Q normally rest, on asegmental pad lbavliich is supported by rods 17 pro- )eating toward -thefrontxot the machine' from tliesegnient 9; Character` keys lSare mountedon the, forward ends of key levers' 19, which at their rear endsarepirated on'y :i transverse pivot rod :Etlfivhich is mounted at itsends inthe side platesot'the basejpm- 'tion 1 ot'the m'ain traine.

Said key levers are spaced apaitandguided attheir rear ends by a combplate 21 mo'unted inthe main .frame just back of the'pivot; rod 20 andhaving formed therein a series of vertical slots, one for each' of saidvkey/.le

sesVA vers. The comb plateQl is secured atits l ends to the'sidc platesof the base portionl of' the main frame by screws Q2 passingthrought-ars 23 of said coinb plate and threaded into said side. plates.The key levers 19 are 'guided near their forward ends Vby a comb plate,24 secured to a cross-bai' 25 of the main frame', which cross-bar lies.above the series of keylevers and has 'secured to its under side anarresting pad26. Angular sub-levers 2T are pivoted on a rod 2S that liesbeneath the. series of key levers I 19' and is n-ionnted on its ends in.thel'side Y xvlates` of the vbase portion 1 of the main traine. Cach ofsaid sub-levers has anl upstandingr arni, tothe npperend of which endofa llink 30, the forward endlof Which is pivoted at Y sub-levers 27 hasa rearwardly projecting V3;? 'of each of the sub- :31V to one of thetype bars l2. Each of the arm 32, the upper surface of whlch is engaged'by a member forming part of or mounted on one of the'keylevers 19. Saidmember preferably consists of a roller 33 journaled 'on a headedpin or'screw 34: projecting fronrone side of the key lever 19. The rollers 33are preferably grooved on their rcripheries, the up )er edge of the (armlevers lying in the groove in the periphery oone of the 4,rollers Each'of the sub-levers is formed with a forwardly* projecting arm 35, to

which is conneeted.the upper end of a returning spring 36, the lower endot which is connected to a cross-bar 3'( which 1s secured at lts endsto the. side plates l by screws 38 passing through ears 39 of said bar37 and 'QJ-" threaded into said side plates. The' conf struction is suchthat Awhen .any 'key 18 is e operated the corresponding key lever.'19,is

depressed and the roller 33 on said key lever depresses the rearwardlyextendingv arm 32 of the corresponding sub-lever, thus moving theupstanding arm of said sub-Jever' toward the back of the machine andcausing the'link 30 to swing the corresponding type bar 12 to theprinting point7 all asrindieated Ain Fig. 2. As the arm 32 and the keylever. 19 more about diierent centers, the roller 33' will roll -ashort'distance along the'arm 32 of the sub-lever when the key isdepressed.V The the; upper-ends of ysaid arms into proper re'- lationthe type bars, It results from this construction that Wnhen one of thetype bars vnear the end of the segment is operated by its key lever andsub-lever, the resistance o'-t-lie link 30 on the upper end 0i the sub-'levei` tends, during the key depression, to -turn or twist thesub-lever about its pivotal point in such 'manner as to throw therearwardlyv extending arm 32 thereof laterally toward the center of themachine. This twisting tendency is resisted by the side of the groove inthe roller 33, as Well as by vthe collars 27'," so that the sub-lever isnot allowed to bind'between the two adjacent collars 2. and affords afore and aft movement of the sub-lever without effecting a bindingthereof on its-.pivotal bearings.

A universal bar 40 extends across the machine beneath the arms 32 of thesub-levers.

Y Said universal 'bar is connec'tedfatfits ends- 'to arms 41.Which inturnfarefpivotally-r Y mounted on thel ivot rod '28. 1t; will beperceived thatv w en an; c 4araoter key -is opera-tedthe universalbarl40-is depreed' by the corresppndingsubflever.. Said universal barhasl a 1'earward1y 'extendng cen-- trally, located arm f1.2 and headedscrew threat1 d Vin'toit'near 1pts rear end. Said'serew `passes looselythrough' an elongated slot-44' formed in the having a shouldered lowerend of 'a link45, theup'ptr end of' I lwhich ispivoted'to the forwardend of an I Y arm 46 that extends toward the front of the.'

machine from the dog rocker 7. The screw 43 does notnormally stand inthe bottom of theoslot 44, but stands a short distance above the bottomoifisaidl slot so that. the link 45 and the dog 1 Joker 7 do not beginto move until thefkey even sub-lever, andtype bar Vhave already made apart of their stroke and have acquired some momentum. .In order that theamount of lost motion between the screw 43and the1bottom` of the lf slot44 mayQbereguIated'," the .lower end of the link 45 is made in alseparate piece from the upper end of said link and is threaded on to'theupper end-of said link so that the length of the link may be adjustedby screwing said lower endnp or. down. The dog rocker 'and universal barare restored to normal position by a spring-47,- compressed betweenthebracket 8 and the'upstanding vare mounted. l e

In most front-strike type actions there are a number of loose jointsbetweenl the key and arm of saiddog rocker on which the dogs 6 e thetype bar and itis desirable to have as -iew as possible of these loosejoints between ,the type bar and the universal bar. -It is desirable tohave the escapement, which is controlled by the universal bar, let offas soonv as possiblev after the type` reboundsv l.from theplaten and`every loose joint bei tween the typebarand the universal bar lessonsthe precision with which the letotf can be controlled. In a type actionof 'the general character set forth in this case-the universal barcontrols .the escapement morev exactly if said universal bar' isoperated by the sub-levers than it does if operated by the key levers.It is not new to operate the universal bar by means'of the sub-levers ofa front-strike typewriter, but it is new to mount Athe universal barbeneath the horizontal arms of said sub-levers, and this is the simplestscheme for this purpose with which I am acquainted. The universal bar isthus simply a straight bar lying beneath horizontal parts having an upand down motion; and this is a simpler construction than those in whichthe universal bar moves horizontally and is operated by the upstandinarms of the sub-levers.
